Embodiment Construction

[0015] The invention includes a water meter, an IC card, an IC card holder, a microprocessor with a solidification program, a memory (or a single-chip microcomputer chip with a CPU and a memory), an IC card read-write device, a control circuit, and a display device. Among them, the microprocessor is the hub of the entire control circuit, and it and the program solidified in it control the reading of the IC card and the opening and closing of the actuator of the valve. The above-mentioned microprocessor is selected as Microchip PIC16CF72 chip, which is connected with the IC card reading and writing device through the pins P27 and 26 to realize the reading and writing operation of the IC card; connected with the control circuit through the pins P15 and 16, the control circuit is connected with the motor and Low-noise, high-torque transmission mechanism is connected to control the opening and closing of the valve actuator. The display device is a liquid crystal display screen con...

Abstract

The invention relates to a prepaid smart IC card water meter capable of stepwise metering and billing in the field of water supply technology. Its main feature is that by setting a stepwise water price program for water use, different pricing can be implemented at different consumption stages to meet the shortage of water resources. The need for rational water use and scientific management in the region is conducive to water conservation.

Description

technical field [0001] The invention relates to a meter in the technical field of water supply, in particular to a prepaid intelligent IC card water meter capable of realizing stepped metering and billing. Background technique [0002] The existing IC card water meter uses the IC card as the media to load the user information into the water meter at one time, and convert the water consumption into water consumption according to the initial setting of the single water price, and store it in the water meter. to zero. my country has a vast territory, and there are great differences in water resources in different regions. In areas where water resources are scarce, it is extremely necessary to realize quantitative price-based water supply. The existing water meter water price is single, and it is impossible to realize the price-based setting at different stages of the total water consumption according to the actual situation of each region. . Contents of the invention [0003...
